The idea is that you get rid of all of the &&ing and ||ing that 
tends to make #ifdefs really hard to follow and error-prone. And 
by having each version fully separate, changing one version won't 
break another.

Now, that comes at the cost of forcing you to duplicate a lot of 
code, which almost everyone other than Walter thinks is worse 
than the risks associated with merging similar versions together, 
but as far as I can tell, Walter is completely consistent in his 
arguments.
